The step-by-step procedure for drought monitoring using the Vegetation Condition Index (VCI) is available to follow using R-Studio, Python and ENVI. These methods were developed to give the user flexibility to choose which of the open source tools is more practical and convenient. The scripts available in R and Python derive the VCI from the Enhanced Vegetation Index (EVI) while the step-by-step instructions in ENVI (5.0) are based on the Normalized Differentiated Vegetation Index (NDVI).
